About Steel

Compare over 50 grades of steel and cast iron to find the right material for you—all with material certificates for traceability.

Carbon Steel

Low-Carbon Steel Rectangular Tubes

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. These tubes are often fabricated into parts that don’t require high strength, such as frames, supports, and raceways.

Low-Carbon Steel U-Channels

Also known as mild steel, low-carbon steel is easy to machine, form, and weld.

Zinc-Galvanized Low-Carbon Steel U-Channels

These U-channels are zinc galvanized for good corrosion resistance.

Low-Carbon Steel 90° Angles

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and edge protectors.

Zinc-Galvanized Low-Carbon Steel 90° Angles

These 90° angles are zinc galvanized for good corrosion resistance.

Low-Carbon Steel T-Bars

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Low-Carbon Steel Round Tubes

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit.

Ultra-Strength Carbon Steel (AHSS) Round Tubes

The same steel used in automobile bodies, this AHSS (advanced high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel.

Alloy Steel

A992 Alloy Steel H-Bars

Also known as W- and WF-beams, H-bars have wide flanges for strength. Made of alloy steel, they’re often used in machine bases, platforms, and frames.

Easy-to-Weld 4130 Alloy Steel Rectangular Tubes

Made from 4130 alloy steel, also known as chrome-moly steel, these tubes have low carbon content for good weldability. They’re often used for building frames and supports, since their flat sides make them easier to bolt than round tubes.

Easy-to-Weld 4130 Alloy Steel Round Tubes

Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames.

A992 Alloy Steel I-Beams

Made of stiff alloy steel, these I-beams are often used in construction, framing, lifting, and hoisting applications.

Multipurpose 4140 Alloy Steel Round Tubes

Made from alloy steel, also known as chrome-moly steel, these tubes resist fracturing from repeated stress. They’re used for a wide range of parts, including cylinders, rollers, and frames.

Hard Wear-Resistant 52100 Alloy Steel Tubes

Easier to machine than 52100 alloy steel rods, these extremely hard and wear-resistant tubes are often used to create bearings, bushings, and other cylindrical parts that are under constant stress. They’re also known as chrome steel.

Easy-to-Machine Gray Cast Iron Round Tubes

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, rollers, and bushings.

Steel Hat Channel

In addition to creating space inside walls or ceilings—to prevent dampness or make room for insulation—these channels can also be used to level or resurface them.
